>this morning, Tiangong-1 was orbiting between 178 and 189 km (117 mi.) in altitude, having descended 7 km in the past 24 hours

The Wikipedia page lists its intended perigee and apogee at 168-178km. So either Wikipedia, or the article, are mistaken.

For reference, Salyut, the old Russian space station, was in orbit at 220-280km. The ISS and most others orbit around at a little over 400km.

You're looking at it's current orbital parameters - if you look further down you'll see how the orbit degraded from approx 350km in 2017
